Nestling within its 18k rose gold case, the L.U.C Lunar Twin timepiece exudes a captivating poetry. The moon phase complication of the chronometer-certified movement is so accurate that the difference between the actual lunar cycle and the indication is just one day every 122 years. The original display means that moon phases for both...Northern and Southern hemispheres are simultaneously visible.
